The application be that Dec 16, application number in 2003 are 200380109309.4 the applying date, denomination of invention divides an application for the application for a patent for invention of " signal conditioning package and information processing method ".
Technical field
The present invention relates to a kind of signal conditioning package and information processing method and computer program.More specifically, the present invention relates to a kind of signal conditioning package and information processing method and computer program, wherein, be connected in the configuration of the communication between the equipment of network such as home network (home network) in execution, the details of the metadata of characteristic (attribute) information of the content that has as content providing server can be offered customer side, and at customer side, make it possible to realize the renewal of metadata or based on more suitable content obtaining and the reproduction processes of metadata.
Background technology
Become more and more popular along with the current era data communication network becomes, use more and more widely in the family so-called home network, wherein electric home appliances, computing machine and other peripheral cell are networked so that can intercom mutually between them.Thereby allow communications between networked devices share data processing function and between them the home network of sending and receiving content provide convenience to the user and be comfortable.Being expected in the future home network will become and more come widespread use.
Agreement as being suitable for this home network configuration has known universal plug and play (Universal Plug and Play, UPnP).Universal plug and play (UPnP) permission user need not complex operations and just easily makes up network and allow the user on the networked devices to need not the operation of difficulty and the service that is provided by institute's connection device with regard to receiving is set.Other advantage of UPnP is that it does not rely on the OS (Operating System, operating system) on the equipment and can add at an easy rate equipment.
Under the UPnP environment, follow the defined file of XML (eXtensible Markup Language, extend markup language) for being identified in mutually exchanged between equipment.Scanning of UPnP is as follows:
(1) addressing is processed, and is used for obtaining the ID of himself equipment, for example the IP address.
(2) find to process, be used at the network search equipment, in case receive from the replying of equipment, obtain this information such as device type and function in replying that is included in.
(3) services request is processed, and being used for provides service based on processing the information inquiry facility that obtains by discovery.
By carrying out above-mentioned processing procedure, the application apparatus (applying device) that is connected to network can provide and receive service.The equipment that newly is connected to network can be carried out above-mentioned addressing and process to obtain device id, carries out and find to process to obtain information about the miscellaneous equipment that is connected to network, send services request based on the information of being obtained to miscellaneous equipment.
For example, when the user wishes when customer side equipment reproduces content such as music data and the view data that is stored in the server, customer side sends the request of obtaining to server, request server sends the content information that is stored in the server, for example, various types of content character information, title or artist's name such as melody or film, data compression pattern information (ATRAC: adaptive transformation encoded acoustic, MPEG: Motion Picture Experts Group, etc.) and copyright information (if necessary).This characteristic information is known as metadata or metamessage.
In response to the request from customer side, the metadata (characteristic information) of the content that server transmission server has is to customer side.Based on the metadata that obtains from server, according to predetermined display routine displaying contents information on the display of customer side equipment.For example, in the melody tabulation of display demonstration by artist's name and title composition.Based on demonstration information, the content that the user checks or selection will be reproduced and transmission content transmit a request to server.Server receives the content requests from customer side, and sends this content to customer side according to the request that receives, and the content that the customer side reproducing received arrives.
In this way, can be stored in from the miscellaneous equipment access that is connected to network content in the server the home network.For example, connect based on the UPnP of above-mentioned simple device syndeton and the equipment that connects can obtain content.When this content is cinematic data or music data, the televisor that connects as network access device or player so that the user can watch TV or listen to music.
But, in UPnP between the defined equipment for example between server and customer side the metadata of sending and receiving be unified (uniform), thereby in having the equipment of various functions, may be insufficient from some metadata that server receives.
For example, the metadata that receives from server, may there be the data that allow renewal processing such as rewriting, deletion and add.Under the environment of existing UPnP, for example based on the metadata that receives from server in the situation of displaying content list on the customer side equipment, not have to carry out and be used for judging which data of permission are rewritten or the transmission processing of the data of processing can be deleted and add to which data.Thereby, need the user to carry out the processing of test (try-and-error) type, wherein in fact the user attempts the executing data input and carries out thus the metadata updates processing in each data field.
As with such as the relevant disclosed related art of the processing of the rewriting of metadata and interpolation, can quote for example patent documentation 1 (the public announcement of a patent application No.2001-292413 that Japan has announced).In patent documentation 1, following structure has been described, wherein each job step in the image processing system of the collections such as manufacturing company, editor/processing and the store video/audio frequency of new program writes metadata.For example, when outside broadcasting van moves to news report (coverage) place, the metadata of considering in the planning step is sent to the image pick-up device in news report place from the data administrator in broadcasting station, and in the report step, except the metadata that sends from the broadcasting station, also have the metadata that automatically generates to be recorded on the recording medium.In this way, show so a kind of structure, each step that this structure makes it possible in recording and reconstruction device, editing device etc. is carried out the processing of writing of all kinds metadata.But, in this related art, there is not to show clear any device of indicating following ranges, in described scope, can carry out the renewal of the metadata of permission in each step or device such as rewriteeing, add, deleting.
In addition, metadata comprises various data item, such as title, reproduction time, data recording date and time, and to each definition of data item the data pattern of license (enable) input; For example, only have text data, only have numerical data or only have integer data to input.In addition, in the situation of numerical data, can define the value scope that to input.In the situation of text data, can define the number of input character etc.But, in existing UPnP, owing in the sending and receiving metadata, between equipment, do not have the notifier processes of the data pattern etc. of execute permission input, thereby need foregoing prototype version to process.
In addition, about the server of content to customer side is provided, each content that can provide server usually provides such as view data and provides server and voice data that the server of server is provided.These each servers have the content of different pieces of information pattern.For example, ATRAC3, ATRAC3plus, MPEG1, MPEG2, MPEG4 etc. can be used as example.
Although the discovery of customer side in UPnP can be obtained the content type that server has in processing, be inadequate for the means of the details of obtaining data pattern.Even having notified these data of customer side is mpeg datas, comprise that it is that MPEG2 or the notifier processes of the details of MPEG4 also are inadequate, this adversely causes unsuitable data selection or the data sending request of user on the customer side.

In this way, the attribute information that sends to customer side from server comprises that wherein the information of the pattern of processing and the value that can arrange is upgraded in license.
Get back to Fig. 4, proceed the description of the processing sequence between server and the customer side.When server sends for example above-mentioned XML data shown in Fig. 5, and customer side is when receiving these data, and the customer side machine shows the content information tabulation of XML-based data at the display of customer side machine.
In the Graphics Processing of this content information tabulation, but based on for wherein permitting of above-mentioned every attribute information setting upgrade the pattern processed and settings information carry out tabulation and show.The demonstration example of content information tabulation has been shown among Fig. 7.
By demonstration differently is set, for example, show not rewritable area with white displays writable area territory and with grey, the user is appreciated which field can rewrite.Example shown in Fig. 7 only is an example, and can adopt the structure that wherein shows the field that can rewrite, add and delete with the different colours setting by color.In addition, not only by the color demonstration but also by various types of graphics process, thereby but the edit pattern that each field can be identified each field can be set.
For example, the field 351 shown in Fig. 7 is the data fields that can rewrite attribute information, and field 352 is the data fields that do not allow the attribute information that rewrites.In addition, in the data field 353 of the attribute that has defined the digital value that can arrange, shown the numerical data 1,2,3 that can arrange, and be defined as the field 354 of the value that can arrange for wherein four values (NotYet), (Timed), (Recording), (Recorded), be used for showing that wherein the Graphics Processing that provides the structure of the value that can arrange as combo box is possible.This carries out (referring to Fig. 5) based on the XML data that receive from server in the customer side machine.
The Graphics Processing pattern of the contents list shown in Fig. 7 is an example, and the various demonstrations except this Graphics Processing pattern are possible.Please note, with the corresponding edit file of every attribute information that receives from server, namely various types of information such as whether permit rewritings, whether permit add or the input data layout of deletion, license, the value that can arrange by the pattern demonstration that can identify them with the user.This Graphics Processing allows the user effectively to carry out suitable Data Update.
Get back to server among Fig. 4 and the processing sequence between the customer side, proceed explanation.At step S23, customer side is carried out content information based on the attribute information (XML data) that receives from server and is shown (for example, Fig. 7).If necessary, then in each field executing data upgrade such as data rewrite, add, deletion.
In addition, at step S25, the attribute information that will comprise the data after the renewal sends to server.Attribute information after server will upgrade is stored in it self the storage unit.That is, process with the renewal of carrying out metadata corresponding to the respective meta-data of the content of the attribute information after upgrading with the attribute information rewriting after upgrading.In server, finish renewal and process, then at step S26, finish notice to customer side transmission renewal and finish thus attribute information renewal processing.
Describing obtaining of attribute information in the customer side device with reference to the treatment scheme of figure 8 processes and upgrades processing procedure.
In step S111, the customer side device is carried out to the obtain request of server proposition for attribute information.As mentioned above, this is to carry out as the processing that sends the order [X_GETSchema] of for example having added the class appointment to server.
At step S112, customer side receives the attribute information from server as the XML data, and at step S113, based on the attribute information that receives, customer side produces demonstration information (UI) and shows this demonstration information at display, in this demonstration information (UI), the user can identify and upgrade license/prohibited mode, that is, whether permit that rewriteeing processing, interpolation processing or deletion processes the data layout of permission and the data value of permission.For example, demonstration information is the contents list of describing with reference to figure 7.
At step S114, the user upgrades the content information executing data on the display that is presented at the customer side device and processes, and the information after step S115 sends renewal to server.When the renewal in the server is finished dealing with, at step S116, receive as renewal finish dealing with the notice reply (Ack) to finish processing.
As mentioned above, structure of the present invention is such, for the individual element of composition as the metadata of the characteristic information of content, namely for every attribute information, the edit file of its permission is added to the XML data and sent to customer side from server, then in the customer side device, based on the XML data that receive, generate and show that as user interface editor that user wherein can identify every attribute information allows the content information tabulation of pattern.Thereby the user can be effectively and is positively carried out suitable editing and processing to every attribute information.
(reproducing content based on the attribute information that obtains is specified)
As mentioned above, in structure of the present invention, from server detailed attribute information is sent to customer side.Foregoing description focuses on that the editing and processing of attribute information provides in the customer side, and customer side can be processed by receiving from the more suitable content playback of the detailed attributes information and executing of server.
